Neuromedin S (NMS) is a neuropeptide identified as another endogenous ligand for two orphan G protein-coupled receptors, FM-3/GPR66 and FM-4/TGR-1, which have also been identified as types 1 and 2 receptors for neuromedin U structurally related to NMS. Although expression of NMS mRNA is found mainly in the brain, spleen, and testis, the distribution of its peptide has not yet been investigated....

The discovery of neuropeptides has resulted in an increased understanding of novel regulatory mechanisms of certain physiological phenomena. Here we identify a novel neuropeptide of 36 amino-acid residues in rat brain as an endogenous ligand for the orphan G protein-coupled receptor FM-4/TGR-1, which was identified to date as the neuromedin U (NMU) receptor, and designate this peptide 'neuromed...

The neuromedin U (NMU) system is composed of NMU, neuromedin S (NMS) and their receptors NMUR1 and NMUR2. This system is involved in the regulation of energy homeostasis, neuroendocrine functions, immune response, circadian rhythm and spermatogenesis. The present study aimed to investigate the possible role of the NMU system in regulating functions of cultured rat calvarial osteoblast-like (ROB...

Neuromedin S (NMS) and neuromedin U (NMU) are regulatory peptides that share the C-terminal amino-acid sequence and act via common G protein-coupled receptors called NMUR1 and NMUR2. Semiquantitative real time-PCR showed that in the rat hypothalamus and testis NMS gene expression was markedly higher than that of the NMU gene, while the reverse occurred in the anterior pituitary and thyroid glan...

The pars tuberalis (PT) is part of the anterior pituitary gland surrounding the median eminence as a thin cell layer. The characteristics of PT differ from those of the pars distalis (PD), such as cell composition and gene expression, suggesting that the PT has a unique physiological function compared to the PD. Because the PT highly expresses melatonin receptor type 1, it is considered a media...

The basal ganglia of rhesus and squirrel monkeys were examined using immunohistochemical techniques with antibodies against the neurotensin-related hexapeptides Lys8-Asn9-Neurotensin(8-13) (LANT6) and Neuromedin N. A high percentage of neurons in both segments of globus pallidus and many large neurons of the striatum were found to label for LANT6, but not Neuromedin N. Previous studies have sho...
